[0006] The purpose and effect of an anti-seepage and anti-cracking structure for building exterior walls of the utility model are achieved by the following specific technical means:
[0007] An anti-seepage and anti-cracking structure for building exterior walls includes a first splicing wall and a second splicing wall. An installation groove is opened at the lower part of the first splicing wall. An inclined surface is opened on the inner wall of the installation groove. Sealing strips are installed on both sides at the highest part inside the installation groove. A convex block is arranged at the upper part of the second splicing wall. The two sides of the convex block are beveled edges and are adapted to the inclined surface. Installation grooves are opened on both sides at the upper part of the convex block. The size inside the installation groove is adapted to the size of the sealing strip.
[0008] Further, the size of the convex block is adapted to the inner size of the installation groove. When the first splicing wall and the second splicing wall are spliced, the sealing strip can enter the inside of the installation groove.
[0009] Further, positioning grooves are opened on both sides of the first splicing wall where the installation groove is located. Positioning plates are arranged on both sides of the convex block on the second splicing wall. The thickness of the positioning plate is adapted to the thickness of the positioning groove. The positioning plate can be inserted into the inside of the positioning groove.
[0010] Further, a first connection hole is formed in the first splicing wall, a second connection hole is formed in the positioning plate, and the first connection hole and the second connection hole are connected by a fixing bolt.
[0011] Further, an installation chamber is formed between the two sides of the convex block and the positioning plate. An installation wedge block is provided between the positioning groove and the installation groove. The installation wedge block can be inserted into the interior of the installation chamber, and the fixing bolt can be connected to the installation wedge block.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] In the utility model, the positioning groove is aligned with the lower positioning plate, and then the first splicing wall is gradually moved downward so that the positioning plate enters the interior of the positioning groove. At this time, the convex block enters the interior of the installation groove. The inclined surface can keep the center corresponding when the convex block enters. At this time, the centers of the first splicing wall and the second splicing wall are corresponding. When the sealing strip enters the interior of the installation groove, it can prevent moisture from entering the connection part, improving the overall anti-seepage performance.
